Pf 2.0

WhatPF 2.0 versus PF 3.0 ....is there a way to access the posts made in PF 2.0. I am a long time user of the physics forum and I have been looking for posts that perhaps I cannot find because there was an overstart in the physics forum that during my abscence i was not aware of. Is it true that a person can purchase the PF 2.0 in the form of a cd rom with a 20 dollar donation?
